Does caffeine actually hurt your sleep, or is it stress? Outcome: Statistically rigorous personal evidence base.
Does caffeine actually hurt your sleep, or is it stress? Run a real RCT on yourself. 28 days.
Hassan suspects afternoon caffeine wrecks his sleep. He opens /deep-engines → N-of-1 Lab and designs a 28-day randomized crossover: 14 randomly-assigned days with afternoon coffee, 14 without. The engine integrates with Body Companion sleep logs + HRV. At day 28, it runs a paired t-test (p < 0.05 threshold) and concludes: 'Afternoon caffeine reduces your sleep efficiency by 11.2% (p = 0.003).' He stops. The engine catalogues his experiment in a personal library — habits, supplements, work schedules — he ends up with a personal evidence base unique to his body. Distinct from any habit tracker: statistical rigor (randomization + crossover + p-values) at personal scale.
